I think the iPad is pretty much the perfect tablet for me. It has come such a long way since I used - and hated - the iPad 2 years ago. The design is beautiful, the display amazing. It's very fast and responsive. Other than iOS 6 which I found disgusting, iOS7 is gorgeous.
With Office for iPad, the great Spotify app, OneDrive integration that's at least as good as on Windows Phone (and gave me additional 3GB space just because I upload my pictures to OneDrive, something you also get on Android but not on Windows Phone!!!), and the general app quality (for example from the newspaper I have a subscription now, an app only available on iPad) it makes me really happy.
And the battery lasts for hours and hours, even when playing a complex 3D game.
And I forgot to write about the speakers, of course they are not great regarding their size, but they are really good enough to enjoy music or games.
